ABSTRACT
Like many architects today, Le Corbusier, was fascinated by the role that light had to play in his buildings. This chapter discusses three-point lighting, which is a very versatile, flexible and manageable approach. It focuses on techniques, which culminated in using the Light Tracer. Radiosity is just one method of rendering indirect light, which can also be calculated using hybrid global illumination and photon mapping algorithms. These methods of rendering can produce startlingly realistic results, which can sometimes be confused with photographs. Mental ray allows reuse of the photon map in subsequent renders, which is useful for things like fly-throughs, where the lighting does not change over the course of an animation. Flickering neon signs have been used time after time in films, particularly those involving private detectives it seems, to give the scene grittiness and a recognizable sleazy location.
